This podcast features Richard Norris talking about the effects of climate change on our oceans and how looking at the past can help us understand how our oceans will be affected. Richard Norris talks about mean climate states and transit climate states and how in the past they have existed. He describes the mean climate state as being a time in history where the CO2 concentration in the atmosphere was much higher than it is today. He mentions though that although the CO2 concentration was much higher, the world was like this for millions of years and the ecosystems went into equilibrium. A transit state is one in which the climate goes from being relatively cool to a warm climate in a short amount of time, which is what Earth is currently going through. Richard states that climate changes happen over a wide length of time because many parts of the world don’t heat at the same rate. By looking at how the oceans and land adjusted to heating in the past over many years, it will help us understand how our earth is likely to heat and what areas will be the most effected. Richard states that as climate changes, he believes the oceans will not be as oxygenated, sea levels will be about 50 meters higher, and reef ecosystems will probably dwindle. Finally Richard states that the ocean food chains will become much longer.
